The access control card can be used for more complex applications, such as a 13.56 MHz contactless smart card, which not only binds cardholders, but also enables two-factor authentication with the reader to ensure security. In addition, the secure storage capabilities of contactless smart cards allow them to support a wide range of applications, such as biometrics, micro-electronic payments, and secure PC desktop login. Until now, we still need such cards to identify the rules of the access control system stored between the reader and the central controller, and perform secure identification to determine whether to open the door.
Phone access card
The first step to supporting portable authentication is to establish a reliable authentication framework that verifies all terminal devices (such as credential cards, printers, card readers, and NFC-enabled mobile phones) in the network so that data can be exchanged between end devices. Secure transmission. HIDGlobal's TrustedIdentityPlatform (abbreviated as TIP) is one of the frameworks that supports secure data transmission. TIP has established an extensible framework and delivery infrastructure that provides three key features: ready-to-use secure access between hardware and software, best-in-class key management and security setup processes, and seamless integration with IT infrastructure.
A trusted framework must use a secure, open, and independent SecureIdentityObject (SIO) data structure on the credential side; a corresponding SIO decoder is used on the side of the reader. SIO is a standards-based, device-independent data object that can be stored on any number of authentication devices. The SIO and SIO decoders perform functions similar to traditional cards and readers, except that the data structures used are more secure and flexible.
Rod Cylinder Lens
Rod cylinder Lens is polished on the circumference and ground on both ends. Optical performance is similar to a Cylindrical Lens . Collimated light passing through the diameter of the rod cylinder lens will be focused into a line. N-BK7 and UV Fused Silica substrates are available for a variety of UV, Visible and NIR applications. Also we supply kinds of Plano-Convex Cylindrical Lens,Plano-Concave Cylinder Lens,Double-Convex Cylinder Lens,Double-concave Cylinder Lens, Meniscus Cylinder Lens ,Rod cylinder lens,special cylindrical lens etc. these cylindrical lens and components are available in a range of micro sizes for integration into a host of OEM applications.
Custom sizes, variations in polishing/ ground surfaces and additional coatings on cylindrical lens are available upon request, please contact our Sales Department for details.
